Despite spending years performing stand-up, comedian ARIES SPEARS, in town Thurs.-Sun., APRIL 26-29, has still spent much of his career regarded as "the black guy from 'Mad TV.'" But after a standout performance on HBO's "Def Comedy Jam" and several radio appearances, he is now respected as one of the finest impressionists currently working the circuit. He does a great Bill Cosby, a dead-on Don King and the five-minute bit in which he emulates rappers DMX, LL Cool J, Snoop Dogg and Jay-Z became a viral hit and boosted him to new levels of fame. $15-$20. Thurs., 8:30 p.m.; Fri.-Sat., 8 and 10:30 p.m.; Sun., 8 p.m. Funny Farm Comedy Club, 608 Holcomb Bridge Road, Roswell. 770-817-4242. www.funnyfarmcomedyclub.com.
